Yarl’s Wood IRC
IRC Concerns
2024 · Published 5 Aug 2025 · 388 prisoners
Self-harm: 57
Staff assaults: 7
Yarl's Wood IRC experienced a 40% increase in detainee throughput in 2024, operating close to its 444-person capacity. While staff are commended for humane treatment and effective incident management, concerns persist regarding high levels of violence, inappropriate detention of vulnerable individuals, and poor information sharing. The Board highlights issues with prolonged detention, slow casework progression, and the inappropriate use of the CSU for mental health cases, noting that staff recruitment and retention remain challenging.
Key concerns identified
- Persistent high levels of violence, linked to the proportion of Time Served Foreign National Offenders (TSFNOs) and detainee frustration over prolonged detention.
- Inappropriate detention of vulnerable individuals with significant mental health problems, including their prolonged housing in the Care and Separation Unit (CSU) due to a shortage of specialist beds and poor information sharing from prisons.
- Safeguarding concerns, including the shared CSU for male and female detainees and issues with visual access between male and female units leading to unwelcome comments.
- Lengthy and uncertain detention periods, especially for TSFNOs, contributing to detainee frustration, anger, and deteriorating mental health, compounded by slow casework progression and bail accommodation delays.
- Inconsistent application of rules and potentially inhumane treatment, such as threats of force for administrative transfers and routine handcuffing of detainees during hospital visits.
- Challenges in healthcare provision due to a lack of medical history for new arrivals, particularly from the prison estate, which delays essential medication and assessment.

Yarl's Wood IRC experienced a challenging year with a marked increase in violence and self-harm incidents, linked to higher occupancy and a greater proportion of TSFNOs. The Board raised significant concerns about the length of detention, the fragility of the centre's infrastructure, and the unsuitable environment of the CSU for detainees with mental health crises. Despite staffing improvements, issues persist with communication about immigration cases and the oversight of Rule 35 reports.
Key concerns identified
- There has been a marked increase in violence at Yarl’s Wood, linked to increased occupancy and the proportion of Time-Served Foreign National Offenders (TSFNOs).
- The centre’s fabric has been exposed as fragile during major incidents, raising questions about its fitness for the purpose of detention.
- Length of detention remains a significant issue, with increasing periods for both men and women, and poor communication about case progression contributing to detainee frustration.
- Detainees with severe mental health crises are being kept in the Care and Separation Unit (CSU) whilst waiting for transfers to external mental health beds, in an environment deemed unsuitable.
- There is little or no oversight or auditing of Rule 35 applications, making it unclear which governing body ensures their quality.
- Women on the Nightingale unit feel exposed and uncomfortable due to men on the Crane unit being able to see them in the outdoor exercise area.

The Board commends the centre's management for maintaining a safe environment with low Covid-19 cases, high quality healthcare, and generally fair treatment.
